Stages & Grits3 (diamond sharpening, diamond honing, resin polish)
The BLACKBADGE BKS020 is a 3-stage electric knife sharpener using 100% diamond abrasives across stages 1–2 (sharpening/honing) and resin polishing disks in stage 3. It applies a fixed 20-degree edge angle with spring-guided slot holders to maintain consistent contact along the blade length. Designed for straight-edge kitchen knives (Western-style), it operates via a stable DC motor—no overheating reported—and aims to restore dull blades in 3–6 passes per slot.
Best for: Home cooks sharpening standard chef's knives, paring knives, and utility blades; users seeking fast, guided sharpening without the learning curve of whetstones.
Not ideal for: Serrated blades, Japanese single-bevel knives, or users wanting adjustable angles. Like most entry-to-mid electric sharpeners, it removes more steel than honing alone and may over-grind if misused.
